The hard part about automating the responses is that most companies haven't put in the large amount of investment necessary to fully automate data provenance. I'd bet that most companies have enough data to actually figure out what is about which user if push comes to shove, but imagine having to crawl through your 5-10 years of accumulated ORM and ETL hackery to fully automate the ability to swim upstream through all of the dark corners of your microservices to pull that data together. I'm obviously exaggerating a bit, but for companies like Blizzard that have been continuously developing Battle.net for over two decades, you can bet there are some dark corners in the data pipeline.
